It’s no longer just about what’s happening on the screen. 4DX cinema rumbles, rocks, sways, vibrates, smokes, strobes, sprays water, tickles your legs and even introduces smells. The technology has been around for several years but it is now being introduced to US audiences. CJ4DPlex created the first 4DX experience in 2009 and it quickly spread to 115 screens in 28 countries.
